We became recently aware of this issue. It's indeed a sad thing, and there might be an option of disabling VOIP for UAE users, but it's unclear if that will be enough.
It would be nice to apply for a TRA license, but ultimately we cant afford it (applying costs 10,000 AED). If we could get some sponsorship or donations to apply for a license, it could be an option however.

Multi Theft Auto: Vice City's default port was 2003. That's probably what "MultiTheftAuto" refers to.
Multi Theft Auto: San Andreas's default port is 22003, but you also need to open the http port which is 22005.

Please be specific in your responses. How are you going to use it in your server? We need to actually know how you would implement it.
The challenges relate to the fact that FLA requires GTASA to be restarted for each change. I need to know specific, technical/scripting information on what is limiting you and what you were trying to achieve.

Hi guys
@fastman92 has recently engaged with us in order to get his limit adjuster implemented into MTA. Obviously, there are a number of complexities involved in implementing this, and we need to make some important design decisions to achieve this.
So, why do you want to use a Limit Adjuster tool?
Some things I'm hoping to learn:
Are you trying to play MTA with a modified version of GTASA? Do you want the limit adjuster to play mods like GTA:Underground?
Are you trying to use Limit Adjusters with MTA's own Lua engine* functions? (e.g. engineLoadDFF)
Anything else?
Any feedback would be incredibly beneficial to the team going forward.
Cheers
Dan

We don't use Geshi anymore. We now use Google's Prettify library in both the Wiki and Forums. It's normally quite easy to implement into a web site, you just have to add some custom JS includes and custom BBcode tags.
I'll be releasing a Google Prettify compatible MTA syntax highlighter (the one used to link to wiki and colours) in the next few days.
You'll need configure VBulletin or modify the source code to include the following to JS (in our forum software this is achieved by modifying the theme):
<script src="https://cdn.rawgit.com/google/code-prettify/master/loader/run_prettify.js"></script>
<script src="https://cdn.rawgit.com/google/code-prettify/master/src/lang-lua.js"></script> <!-- Lua not added by default, add it-->
<script>
addEventListener('load', function (event) { PR.prettyPrint() }, false);
</script>
Then you'll need to make a custom BBCode to produce the following tag (e.g. configure a [lua][/lua] bbcode):
<pre class="prettyprint lang-lua">--LUA HERE</pre>

I'd advise against TortoiseSVN, there's no need for it. Probably something like GitHub for Windows is much easier to get up and running.
This guide has more or less everything you need to know: https://wiki.multitheftauto.com/wiki/Compiling_MTASA
There's really more much to developing on a large project than simply applying patches. MTA's codebase is very large in nature, and there are likely to be some integration challenges involved as well as harmonizing with our own coding standards. Good luck.

I'm waiting for any more issues/bugs to arise. We recently ported the forum highlighter to the Wiki so the system is shared.
Once things seem stable, I'll release the highlighter on GitHub and it should be very easy for any community to integrate it onto their website.
